BTBS runs battles in a separate Roblox experience. The build maker on this site only checks card costs and compatibility.

Using the local build maker
Set your available BP, select a weapon setup and add only card copies you own. Resolve any over-budget or incompatible-card warnings. Check the SP cost of the action you intend to use; the displayed list is not the SP total for a full battle.
